When [JPEG2000] has been selected in [Color/Gray scale], select [Some degradation] (compress with a format that does not guarantee image quality), or [No degradation] (compress in a format that guarantees image quality). When [Some degradation] is selected, move the knob of the slide bar to the left and right to specify the compression ratio. |

In the case of document is read with [No degradation], the size of the PDF file will be larger compared to the case when [Some degradation] is specified.
When the compression ratio is specified under [Some degradation], the file size will be smaller as the setting approaches [Low quality (High compression)] and larger as the setting approaches [High quality (Low compression)].
